Preheat oven to 425 degrees. Combine apples, maple syrup, flour, vanilla and nutmeg and pour into 9 x 13-inch baking dish. Dot with margarine and bake for 20 minutes. Remove from oven and reduce temperature to 375 degrees. Cut margarine into flour, baking powder and nutmeg mixture until it resembles fine meal (you can use a food processor for this step if you like). Whisk together nondairy creamer, maple syrup and vanilla and add to dry ingredients. Stir until just combined and drop in 1-tablespoon mounds atop hot filling. Brush with melted margarine and sprinkle with sugar. Bake an additional 15 minutes. Best served warm.
